Abstract

Recently, many organizations are utilizing the team system. However, researches on a technique for efficient and effective feedback to improve a team performance is few. This study compared the relative effects of individual and group feedback on the quantity and quality of work performance. The task was to type English documents on a PC computer and both the number of words typed (quantity) and the percentage of correctly typed words (quality) were measured. Mixed design was adopted and 48 participants were randomly assigned to either individual or group feedback condition. Each group consisted of three participants and completed four sessions together. Under the individual feedback condition, each participant was provided with information on his/her own work performance, while under the group feedback condition, three participants were provided with information on their total work performance. Results showed that both feedback were effective to increase the quantity of performance. However, the effect size of treatment was more high under the group feedback than individual feedback. In addition, the accuracy of typed words was significantly improved only under the group feedback condition. Therefore, the group feedback was more effective and efficient than individual feedback to increase team performance. However, more studies are needed to generalize these results, especially, it is necessary to consider the cultural differences and type of task in the future studies.

최근 많은 기업들이 팀제를 활용하고 있지만 팀의 업무 수행 향상에 효과적이고 효율적인 피드백 제공방법에 대한 연구는 부족한 상황이다. 이에 본 연구의 목적은 팀 수행 상황에서 개인 피드백과 집단 피드백이 과업 수행의 양과 질에 미치는 효과를 비교하는 것이었다. 실험 과제는 영어 문서를 컴퓨터에 입력하는 것이었고 수행의 양은 입력된 단어의 수로, 수행의 질은 올바르게 입력된 단어의 비율로 측정되었다. 혼합설계(mixed design)가 적용되었고 총 48명의 참가자들은 개인과 집단 피드백 집단에 무선적으로 할당되었다. 각 팀은 3명으로 구성되었고 총 4회기 동안 함께 과제를 수행하였다. 개인피드백 조건에서는 각 참가자에게 개인의 수행에 대한 정보만 제공되었고, 집단 피드백 조건에서는 팀의 전체 수행 합에 대한 정보만을 제공하였다. 참가자들의 타이핑 속도를 통제한 공변량 분석결과, 두 가지 피드백 모두 수행의 양을 증가시키는 데 효과적이었지만, 효과크기는 집단 피드백이 더 높았다. 수행의 질에 있어서는 집단 피드백 조건에서만 올바르게 입력한 비율이 유의미하게 증가하였다. 따라서 개인 피드백 보다는 집단 피드백이 과업 수행 증가에 좀 더 효과적, 효율적이라고 할 수 있다. 하지만 본 연구결과는 기존의 연구결과와는 상반된 결과로 일반화하기 위해서는 더 많은 관련 연구가 필요하다. 특히 후속연구에서는 문화 차이, 과제 종류에 대한 고려가 필요하다.
